What kind of cord do I need to connect this to my PC?

Got this at a yard sale and want to connect it with my laptop. It didn’t come with a connector cord and I’m not sure what to buy.

ANSWERS:

"Go here and match your socket up and see if one of these more popular cables is what you need. If you don’t see what you need, please post a photo of the socket”
